Whistling light bulb

[Arabhacks]

The light bulb is not arcing, the filament is oscillating.

The coil of tungsten wire can act as an electromagnet and vibrate.

Some otherwise normal light bulbs can be made to vibrate by placing a powerful magnet near.

The flicker bulb, where the filament wiggles back and forth, have a magnet inside.

It has been turned into an arc lamp. Try feeding with a higher voltage...

The lighting circuit was fuse protected. A fuddy duddy circuit breaker would probably trip out

[laurdy]

those cfl's are worse for the environment than the normal type because they contain mercury, and take more energy to make, some also cause radio inteferance on the AM band, i've even had a cfl explode i my bedroom and i've heard of them actually catchng fire

[benchod94]

@laurdy actually they are still better for the environment as most coal power plants spew out mercury to power the old bulbs

It's gonna pop o;

it's dead

Gah, I'm sick of this - mine keep "singing" as well sometimes (not a filament damage as they "sing" even straight out-of-the-box), and it's kinda annoying. Also with a dimmer I removed by now (didn't cut much of the noise however) it kept sounding even louder and the bulbs kept blowing up from time to time, no matter I usually set the dimmer to the max anyway. Afaik my light holder construction has been removed from the production lines due to the internal electrical issues however.

Put a dimmer on a lightbulb and it'll sing to you also.

I love how you said it's dead.

I've got bulbs working in this way as well.

As for whistling, I've often heard bulbs make strange noises (and sometimes flicker) when they are about to fail.

[jovicakluk]

thats bull shit the light bulb would imeadiately melt if this were to happen

[thomasking55]

why?

[jovicakluk]

beacause the gas would get ionised and a plasma would foorm. as plasma is a VERY good conductor there would be a surge of current creastin very very hot plasma

[RudyMe]

Not always, this is something that is very rare! I've had this happen to me too, and no the bulb DOESN'T explode

[form109]

@thomasking55 i Think what jovicakluk is saying is when the Bulb Filiment breaks and continues to light...normally a High Current would cause the Fuse Wires in the Bulb to melt...but in your case the Arc is small enough that the Current Drawn by the Arc isnt high enough to melt those Lead Wires.

[rootbrian]

I agree.

I've managed to resurrect an incandescent bulb by realigning the filament so it made contact.

I'm telling you, it's REAL hard to tap and shake it back in place from where it broke or detached.

bulbs whistle before they die.

[coolbluelights]

in the US we use 120 volts but I heard a bulb do this once, very rare!

these newer energy saving lights, or mini killers as like to call them, are really messing up my eyes, so id love an old lightbulb type :D
